You generally get this error when the loop continuity is broken.

I cannot do a physical test right now, I am not at home, from memory, try this loop continuity test.

Code:

1) create an empty loop by connecting both interface cable together.
2) press: [XEQ] [ALPHA] AUTOIO [ALPHA]
3) press: [ON]                            // calculator off
4) press: [ON]                            // calculator on

No error message should appears and/or calculator wakeup should be fast.
If calculator wakeup take a long time, you may have a defective module/cable.

Check that the printer switch is in ENABLE position. (like the image below)


My time is UTC-5h, I will post more testing scenarios tonight when I am back home.
